What happened
On 9 July 2026 Meta Superintelligence Labs released Muse Spark 1.1 — a multimodal reasoning model for agentic work: tool use, computer use, coding and subagent orchestration. Alongside the model, Meta launched a public preview of the Meta Model API — the company's first ever paid developer API (Meta blog).

The essentials:
- Context: 1M tokens with active management — the model compacts its own history while keeping the steps that matter for the rest of the run.
- Price: $1.25 per million input and $4.25 per million output tokens — roughly a quarter of what top OpenAI and Anthropic models charge (The New Stack).
- Compatibility: the API is OpenAI-compatible, so existing integrations switch over with a minimal code change.
- Access: the preview is US-only, the EU has no access yet; new accounts get $20 in credits. The model is free in "Thinking" mode in the Meta AI app and on meta.ai (MarkTechPost).
Why it matters
- Meta has entered the paid API market. Until now the company gave its models away for free (Llama shipped as open weights); it now competes head-on with OpenAI and Anthropic for developer money.
- Price pressure. A quarter of frontier pricing with claimed agentic quality is another move in the price war started by Grok 4.5 ($2/$6) and GPT-5.6 Terra.
- For vibe coding: the OpenAI-compatible format means you can try the model in existing agents and IDE integrations with almost no effort.
